Id take a few weeks for yourself, then find a 6 month contract. That'll get you back on your feet again professionally and financially. Depending on how the contract rates are in your area, you should then have a small runway again to think about your options. Id avoid committing to anything too big too early.

I don't know the details of your startup, but if possible can you reduce costs / reduce scope of services to the point its self sustainable? If so, go for it. I've regretted shutting down past projects, sometimes a bit of time off can give you new perspectives on things, and you've presumably built some value even if its not realised yet. YMMV but something to think about rather than outright closing it all down.
